Question 36

Fractional Factorial Designs are used to analyze factors to model the output as a function of inputs if Hypothesis Testing in the Analyze Phase was inadequate to sufficiently narrow the factors that significantly impact the output(s).

  1. True
  2. False

Question 37

A Factorial Experiment based on a Level 2 Design with 6 factors would require 16 runs to fully assess the interactions.

  1. True
  2. False

Question 38

A Full Factorial experiment using a 3 level 3 factor approach has been proposed to test the viability of an extrusion machine experiment. How many treatment combinations will this approach involve?

  1. 6
  2. 9
  3. 27
  4. 54

Question 39

Screening experiments are the proper choice when a Belt is faced with the situation of highly Fractional Factorial Designs.

  1. True
  2. False

Question 40

Which statement(s) are correct about the DOE Factorial plot output here? (Note: There are 3 correct answers).

  1. Two factors were operated at 3 levels each
  2. The highest tool age was achieved with metal hardness at high level while keeping the cutting speed at the low level
  3. The design indicated above is a 32 factorial design
  4. The cutting speed and cutting angle are at the low level for the least tool age achieved
  5. All factors had 2 levels in the experiment
